IMPROVEMENT IN PRESERVE-JARS.

Speciiieation forming part of Letters Patent No. 1L-1,752, dated October1S, 1864.

To a/ZZ whom it may concern.:

Be itknown that I, JOHN J. SQUIRE, of Windsor Locks, in the county ofHartford and State of Connecticut,'have invented a new and usefulImprovement in Preserve and Fruit-Jars; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which- Figure 1 is a vertical section of the top of ajar upon which myinvention is applied. Fig. 2 is a plan view of the jarshown in Fig. 1. Fig. 3 is a vertical section of a jar of anotherconstruction upon which my invention is also Shown, and Fig. 4 is a planview of the jar shown in Fig. 3. Y

Similar letters of reference indicate like parts.

The object of my invention is to make the jar for holding and preservingfruit, vegetables, and preserves of every sort more perfect andpractical; and my invention is of such a character as that it can beeasily adapted to the jars in common use. I have shown two forms ormodes of its application, both embracing and founded upon the principleof my invention.

Figs. 1 and 2 represent a jar having a shoulder, c, formed or cut aroundthe interior of its neck, upon which islaid the ordinary gasket, w, forpacking the joint made by the cover.

B is the cover, resting upon the ring x. It has a central hub, b, whichrises to about the height of the neck or mouth of the jar, and a boss,d, on one side, which rises to about half the height of the mouth; Ahole, 2, is made through the cover B and through the boss, and anotherhole, 1, is made through the cover on that side of its hub opposite tothe hole 2. The holes 1 and 2 fall in the line of the diameter of thecover. A circular groove, J, is cut on the inside of the neck of the jarJ, which groove is intersected at opposite sides by vertical recesses irunning down from the top of the neck or mouth of the jar. Inclinedplanes e are formed upon the top of the cover B at points opposite toeach other.

D is a cross-bar fitting upon the central hub, b, and of such a lengthas to pass easily down the recesses t' to their intersection with thegroove J, when it is turned to the right until its ends rest upon theinclined planes e,where by it is raised slightly above the cover, sothat its ends are forced against the upper edge of the groove J. Theeffect of this position of the cross-piece D is to press the covertightly upon its seatthe packing-ring x.

C is another cross-piece of equal length with the cross-piece D, andmade also to t upon the hub b. Its form is shown in Fig. 1, its endsbeing bent down, so as also to fit in the groove J. YVhen it is sunk inthe recesses z' it is to be turned to the left, so as to cover the holes1 and 2. Cork or rubber, or other suitable packing, a, is secured on thelower face of the eross-piece C in such positions as to cover theseholes when the cross-piece is in place.

Figs. 8 and 4 show a jar, whose cover B takes the form of a cup insteadof a disk, as in the other iigures. It iits within the gasket .'12, itssides being conical,so as to make a joint, which becomes tighter inproportion as the cover is pressed down. 1t has a central hub, I), inwhich a screw-thread is cut to enable it to receive a screw, 4, whichpasses through the cross-piece C. The cross-piece in this example of myinvention has also cork or other packing a on its lower face to coverthe holes 1 and 2, which are made in the cover B in like manner as inthe other example. Y

'Ihe operation of the parts is as follows: rlhe jar shown in Fig. 1being lled with fruit or other substance, the cover B is secured uponits seat by the cross-bar D. The cross-piece C is then placed in thegroove J but not over the holes 1 and 2. The cup formed by or at theneck or mouth of the jar is then filled with Sirup or other liquid,which will flow into it through the hole 1,while air will escape from itthrough the hole 2. The cross-piece C is then brought over the holes 1and 2, and the jar is sealed. Should the contents of the jar shrink orcondense on cooling, or be diminished from leakage or from any othercause, the operation of filling it can be ref peated Without removingthe cover B and without allowing the ingress of air, by merely fillingthe basin or cup with the proper liquid; then turn back the cross-pieceC to uncover the holes, when the liquid will enter the jar through hole1', While the air is expelled] through hole 2.

In the example shown in Fig. 3, the operation of expelling the air andlling the jar with sirup or other liquid is the same; but thecross-piece C is secured to its place by means of the screw 4,Whichpasses through it into the boss b, instead of being secured by slippingits ends in a groove, as in Fig. 1.

My invention can be applied also to other forms of jars and to otherforms of Stoppers, Whether the latter t outside or inside the necks ofthe jars or bottles.

I do not mean to restrict myself to the particular construction andarrangement of ingress or egress holes l and 2, as the same effect canbe accomplished upon the same principle I have shown in various Ways.

I claim as new and desire 'to secure by Letters Patentl. Constructing astopper or cover to a preserving-jar or other vessel, so as to form abasin or cup in the neck or mouth thereof, through which is made aningresshole to allow liquid to flow into the jar, and an egresshole forthe escape of air therefrom, substantially as and for the purpose abovedescribed.

2. The cross-pieceG, in combination with the ingress and egress holes inthe bottom of the cover, constructed and operated substanV tially asabove described.

JOHN J. SQUIRE.
